So it's not original, but it's also not fresh, is what I'm trying to say. If I can get away with a simple fix for a while that would be great as I wasn't planning on doing a trans rebuild at this time. I wanted to wait when I install a 347 motor later this summer. I suppose nobody plans for a trans failure (lol) so if that is the only way to go after I try cleaning the VB and adding some Trans-X then I will cross that bridge at that time.
Thanks for the tips.

PaceFever,
I plan for failures. I built my wife's tranny when I saw that the adjustment was about gone on the front band. It had't given any signs of failing yet. I am building a tranny for one of my Mavericks right now because it has developed "morning sickness" (slow to engage in forward when cold). I will have it ready to install whenthe local community college is doing transmissions next fall. Having said all that and hearing you say that you are not a guy that likes to do a job two or three times I will try to make my answers fit.
The higher than normal oil level wouldn't cause the problem.
If you have reverse when the transmission is cold but no high gear (they use the same clutch) and all the other forward gears work properly when cold (they use the other clutch that high gear does) then I would say it must be the valve body. I would like you to check whether or not the vacuum hose on the modulator (just behind and slightly above the pan) has any oil in it. If there is oil there then you should replace the modulator first. Use a green stripe modulator and don't lose the pin that is between the modulator and the valve. If that doesn't fix the problem then you have replaced a part that was going to give trouble in the future and have not wasted time or money. If that does fix it then I have prevented wasting your money on a valve body that you don't need. If it does nothing then by all indications your valve body needs to be replaced and I would recommend the valve body of your choice from Broader Performance. Get it with the idea of what you will want when you install your new engine. Broader is the best place to go for performance C4s and their parts. I build excellent C4s but I believe that Broader's C4s are at least as good as my own. I would not have a problem buying one for my own use. They are the only rebuilder that I would buy from for my own use.
